h22a4 engine build

I'm new to this site, just got a 99 prelude sh it came with full catback and dc headers.. and i was woundering if you guys can help me out on what I can do more on my car..and I was trying to find the OBD2 to OBD1 swap and I couldn't find it..thanks alot for you guys help.

Yeah, really man. You won't be gaining much for what you're going to spend getting an OBD1 engine in there. Additionally, the chassis that's designed for the while ATTS transmission and axles will might cause a problem trying to get a different engine in there.
